Could not delete /.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/appname/WEB-INF/lib. May be locked by another process

提问by Murilo

I am trying to run an web app. In the beginning it was going well, but I had to delete some jars from the project folder. I didn't delete the jars using eclipse. So, I started to get these errors:

我正在尝试运行一个网络应用程序。一开始一切顺利，但我不得不从项目文件夹中删除一些 jars。我没有使用 eclipse 删除罐子。所以，我开始收到这些错误：

Publishing failed with multiple errors
Could not delete C:/Users/maniceto/Documents/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/fj21-tarefas/WEB-INF/lib. May be locked by another process.
Could not delete C:/Users/maniceto/Documents/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/fj21-tarefas/WEB-INF. May be locked by another process.

I tried to delete my whole project and code it again. But it doesn't work. I also deleted the Tomcat server but again it doesn't work. Then I realized that to "fix" this problem I have to delete this folder:

我试图删除我的整个项目并重新编码。但它不起作用。我也删除了 Tomcat 服务器，但它再次不起作用。然后我意识到要“修复”这个问题，我必须删除这个文件夹：

C:/Users/maniceto/Documents/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/fj21-tarefas/WEB-INF.

C:/Users/maniceto/Documents/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/fj21-tarefas/WEB-INF。

And cleanthe server and the project. But when I close eclipse and open again I get the same error, then I have to do this process.

并清理服务器和项目。但是当我关闭 eclipse 并再次打开时，我得到同样的错误，然后我必须执行此过程。

Anyone here knows how to fix this kind of tomcat bug?

这里有人知道如何修复这种tomcat错误吗？

我不知道这个问题的确切原因，但我通过重新启动系统清除了同样的问题。所以重新启动您的系统一次，它可能会为您的问题提供解决方案。

It may be because you are using C driver and you may need Administration rights to perform operation on this directory, try after change the C drive, in any other drive like D: or E:

可能是因为您使用的是 C 驱动程序，您可能需要管理权限才能对该目录进行操作，请在更改 C 驱动器后尝试在任何其他驱动器中，例如 D: 或 E:

Some of your jars are still loaded into memory, therefor their parent directories cannot be deleted. Check if there are running processes accessing any jars or restart Eclipse.

你的一些 jars 仍然加载到内存中，因此无法删除它们的父目录。检查是否有正在运行的进程访问任何 jar 或重新启动 Eclipse。

Simply delete the server and then add it again,then restart your eclipse.It worked for me.

只需删除服务器，然后再次添加，然后重新启动您的 eclipse。它对我有用。

Eclipse Juno running Tomcat 7 on Win7; kept getting the publish error on a javascript file. Tried renaming the file but that did not work.

Eclipse Juno 在 Win7 上运行 Tomcat 7；一直在 javascript 文件上收到发布错误。尝试重命名文件，但没有奏效。

I deleted my existing Tomcat server, as recommended by Vikash Mudliar, and added a new server instance. That worked and I was able to publish successfully.

我按照 Vikash Mudliar 的建议删除了现有的 Tomcat 服务器，并添加了一个新的服务器实例。那行得通，我能够成功发布。

Close the eclipse and go to below location(depends on your system locaiton)

关闭 eclipse 并转到以下位置（取决于您的系统位置）

C:/Users/maniceto/Documents/workspace/.metadata/.plugins/org.eclipse.wst.server.core/

and delete tmp0directory now start eclipse and it will work fine.

并删除tmp0目录现在启动eclipse，它会正常工作。

In my case this happens only when I trigger Update Maven Project (ALT+F5) in Eclipse and the server instance is running with my app attached.

在我的情况下，只有当我在 Eclipse 中触发更新 Maven 项目 (ALT+F5) 并且服务器实例正在运行我的应用程序时才会发生这种情况。

So You have to remove the app from the server ,turn of the server and the n do the Update Maven Project . If the problem persists Clean helps

所以你必须从服务器上删除应用程序，关闭服务器，然后执行更新 Maven 项目。如果问题仍然存在 清洁有帮助
